It's not unfortunate, it's normal.  Other Lisp dialects have them
both, too.  There is a good reason for this: errors can invoke the
debugger.

Emacs Lisp is not Scheme.  Does continuation-passing style work
usably in Emacs Lisp now?  I don't know for certain, but I would
be very surprised.

If not, let's keep things simple by not trying to define
constructs for that.  That simplicity is very important.
